psp speaker and sound reactive led mod HELP!!

[phaxz10]

hi guys!

i basically want to mod my psp and attach a 4mm speaker using this diagram:



but i dont know where to attach the speakers...
and do i need to add wires or change the resistors??

btw, i will use 11 leds and im new in modding

please help me guys! 

thanks in advance!! 

[Luigus]

do you want to use the LM386 as a Sound Amplifier?

then do something like this, just put in a speker where the leds + and - goes..

and dont double post:

anyone??????

[phaxz10]

thank you for the answer sir.. and sorry for double posting.. but how many LEDs the amp can support??

[Luigus]

this is a QUOTE from JUMBO

They can run the amount you are planning.

I think they can run way over 30...

i haven't tested myself, but that's from a trusted source ^^

thanks for the answer again mr luigus!! i can start my modding now!! thank you very much!!

haha its my pleasure!

have fun!

sir please help me accomplish this mod.. i like to make my other 9 LEDs 'non-sound reactive'.. please correct my diagram and list all the necessary things to have like resistors or anything..

How many leds are gonna go into this PSP!? 

lol, if you want other leds non sound reactive that diagram is correct, you may need to add the appropriate resistor for your LED's, or you can use a different power source.. Since leds normally run on about 2-3 V, i suggest using a different power source. Search on google for a site that calculates the amount of ohms needed to get the led on its right voltage.

Theres a 3.6V next to the plug where the charging port goes into the motherboard, you can user that

[phaxz10]

ok sir.. i will try... but i dont know ho to use led resistor calculator 

[Luigus]

add a 100 ohm resistor between the 5V source and the leds, that should be enogh.

How many leds are gonna go into this PSP!? 

by my count... 20.  11 sound and 9 allways on

[Luigus]

by my count... 20.  11 sound and 9 allways on

Gonna take alot of wiring

[phaxz10]

hi there.. is it normal that the IC becomes hot after turning on the PSP?? and i don't have 191k and 30k,, can i replace it with 180k and 33k??

by my count... 20.  11 sound and 9 allways on

11 blue LEDs only sir..

if i wanted more than 2 sound reactive lights could i jus add more pos and neg leads from where the existing trigger leds are connecting to the lm386?......

Also can the lm386 do 2 functions at once?..... meaning can som lights attached to it b sound reactive and others not or will they all do the same thing

yes

no, wire your soild state leds direct. (using a resistor and or switch)
